s claims. (ci. zas-v1) My invention relatos to nexiblo oonduxts of the variety commonly called hose, and more particularly to the means and methods for joining secon its size but on the manner in which its sections are connected. While` the hose itself bell comes iiatly wrapped when wound on a reel,'the

couplings or ttings joining these sections arebulky and prevent more than a limited length of the hose from being carried by each reel.- Obviously, where the hoseis of a larger capacity,

.o such as may be desirable for land irrigation, it

becomes highly impracticable to carry large couplings, owing to their bulk and form.

with the above situation considered. it is my main object to provide a connection for hose of any size which is capable of' collapsing to the flat form of the hose as the latter is wound on a reel, whereby to enable a relatively long hose to be carried on one reel.

-A further object of the invention is to provide u -a hose connection which enables the hose sections to be joined along a spiral course over an extensive area.

A still further object of the invention is to utilize the well known slide or zipper type of u fastener in the novel type of connection.

An additional object of the invention is to provide means in the hose connection for the sealing of the same against leakage.

AWith the above objects in view and with any d0 other that may suggest themselves from the descriptionto follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which- Figs. 1 and 1a are views of two hose portions about to be assembled, the right-hand portion being in elevation and the left-hand one being in longitudinal section;

Fig. 2 is an enlarged fragment of the'upper u portion of Fig. 1', showing the hose constituents spacedly telescoped and in longitudinal section; Fig. 3 is a fragment of the showing in Fig. 2, with the connection made; and v Fig. 4 is a diagrammatical elevation with the sealing flaps omitted, showing the manner in However, the amount of.. hose capable of being wound depends not only"l which one hoseportion is manipulated for joining it to the other hose portion.

Primarily, the most substantial joint capable to be made' between, two portions of tubing or hoseisby telescoping.'` This is precisely the basic l form of my, invention. However, I secure this kind of a joint by interposing a spiral fastening element between the telescoped hose portions, in o`rder that these may be firmly secured. And further than this, I employ the popular slide fastenl. er or zipper-type connection as the fastening ele-. ment, so as to make it a simple matter to fasten or unfasten the joint by drawing the securing element around in one or the other direction in the. manner of a thread.

Specic reference to the drawing indicates the outer hose portion at I0- and the-inner` one at il. Commonly, the components of the slide fastener'- -are carried by tapes, and the'drawing shows the fastener components at i2 and I3, and the tapes n .-(not shown).

While the parts just described are firmly secured at points. ahead of the fastener zone, the ribbons i4 and i5 also have sections Ila and |511 behind such zone which extend freely into the space between the telescoped hose portions.

In order that the portions of the hose may be joined, they must be'arranged as in Fig. 4. It is here seen that the portion Il is in the normal o form, while the portion I0 has been folded back upon itself on the outside. -The extent of this `fold is to a point where -the fastener spiral be-l tion will serve to pull back'the outside fold upon w l l the inner hose portion I i, so that when the windt ing action is completed the portions will .again be completely telescoped and the fastening therebetween secured along its entire extent.

The connection so far completed does not u separation.

fortify thehose against leakage of its contents. It is for this purpose that the rubber ribbons Il and I5 are provided. Thus, as the fastener is being joined in the spiral course, the free sections Ila and IEa of the rubber ribbons I4 and I5 will not only lie back toward their corresponding hose portions, creating a seal over the related fastener tapes I2a and I3a, butwill also become closely laid upon each other. Now, where the fluid inthe hose is under pressureas is usually the casthe hose portion I I will be dilated to press the components of the hose connection against the hose portion I0 whereby to hermetically seal the joint all along its spiral course.

It is just as well that the novel connection is. not tightly sealed when the hose has been emp- -tied of its contents, since it may then be desirable to separate its sections for transfer to another zone of activity. Thus, it is an easy matter to unwind the joint, so to speak, from the outer edge,`folding back the portion I0 as the unwinding proceeds, the affected plies readily yielding to In conclusion, it will be evident that the novel hose connection is of a character to make the transfer and compact 'storage of hose of any size practicable, since the connection is oi a character to be flattened so as to be compactly wound on a reel with the balance of the hose or so much of it las is carried on one reel.f Thus, the hose or of the joint. s
